Merge tag 'rproc-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc 

Pull remoteproc updates from Bjorn Andersson:
 "This adds support for controlling the PRU and R5F clusters on the TI
  AM64x, the remote processor in i.MX7ULP, i.MX8MN/P and i.MX8ULP NXP
  and the audio, compute and modem remoteprocs in the Qualcomm SC8180x
  platform.

  It fixes improper ordering of cdev and device creation of the
  remoteproc control interface and it fixes resource leaks in the error
  handling path of rproc_add() and the Qualcomm modem and wifi
  remoteproc drivers.

  Lastly it fixes a few build warnings and replace the dummy parameter
  passed in the mailbox api of the stm32 driver to something not living
  on the stack"

= SUBNODES

The adsp node may have an subnode named either "smd-edge" or "glink-edge" that

describes the communication edge, channels and devices related to the ADSP.

See ../soc/qcom/qcom,smd.txt and ../soc/qcom/qcom,glink.txt for details on how

to describe these.





= EXAMPLE

The following example describes the resources needed to boot control the

ADSP, as it is found on MSM8974 boards.



	adsp {

		compatible = "qcom,msm8974-adsp-pil";



		interrupts-extended = <&intc 0 162 IRQ_TYPE_EDGE_RISING>,

				      <&adsp_smp2p_in 0 IRQ_TYPE_EDGE_RISING>,

				      <&adsp_smp2p_in 1 IRQ_TYPE_EDGE_RISING>,

				      <&adsp_smp2p_in 2 IRQ_TYPE_EDGE_RISING>,

				      <&adsp_smp2p_in 3 IRQ_TYPE_EDGE_RISING>;

		interrupt-names = "wdog",

				  "fatal",

				  "ready",

				  "handover",

				  "stop-ack";



		clocks = <&rpmcc RPM_CXO_CLK>;

		clock-names = "xo";



		cx-supply = <&pm8841_s2>;



		memory-region = <&adsp_region>;



		qcom,smem-states = <&adsp_smp2p_out 0>;

		qcom,smem-state-names = "stop";



		smd-edge {

			interrupts = <0 156 IRQ_TYPE_EDGE_RISING>;



			qcom,ipc = <&apcs 8 8>;

			qcom,smd-edge = <1>;

		};

	};



The following example describes the resources needed to boot control the

SLPI, as it is found on MSM8996 boards.



	slpi {

		compatible = "qcom,msm8996-slpi-pil";

		interrupts-extended = <&intc 0 390 IRQ_TYPE_EDGE_RISING>,

		interrupt-names = "wdog",

				  "fatal",

				  "ready",

				  "handover",

				  "stop-ack";



		clocks = <&rpmcc MSM8996_RPM_SMD_XO_CLK_SRC>,

		         <&rpmcc MSM8996_RPM_SMD_AGGR2_NOC_CLK>;

		clock-names = "xo", "aggre2";



		cx-supply = <&pm8994_l26>;

		px-supply = <&pm8994_lvs2>;



		memory-region = <&slpi_region>;

		qcom,smem-states = <&slpi_smp2p_out 0>;

		qcom,smem-state-names = "stop";

        };
